Question

which of the following is a key component of user interface (ui)?

Explanation:

Buttons are a key component of a User - Interface (UI). They are used for user interaction, allowing users to perform actions like submitting forms, navigating, etc. Data types are more related to programming and data handling. Algorithms are sequences of steps for solving problems and not a direct UI component. Code structure pertains to how code is organized in a program and not a UI - specific element.

Buttons
